Alternative Way to Check link every Second?
Posted: Thu Oct 24, 2019 12:58 pmHi there! I am new here, not noob for Arduino but noob for esp8266.
Have Nodemcu v3 (Lolin), Trying to control door lock with internet. MY current solution is very straightforward:
1. Check a http link every 3 seconds, (ex. Look a txt file on net, with get request)
2. If its "1", send HIGH to relay output.
3. Send another get request to php file to make it 0 again.
But i think there has to be another solution. Without checking it every 3 seconds, There must be something like push to Nodemcu some message with php or something. Are there any alternatives to my solution? Thanks!
